Theatre Design & Technology - Winter 1999 - 51

Gripsholm theatre is the
most recent and the smallest
ofthe three extant theatres;
its wing change mechanism

is also the simplest.

The Court Theatre at Gripsholm Castle
Although this Swedish castle dates from the sixteenth century, its importance to theatre history began in 1777, when King Gustavus III bought tlle castle from his
mother, Queen Louisa Ulrika, and instructed architect Carl Fredrik Adelcrantz to
build a small tlJeatre in tlJe top of a tower which had a diameter of about 45 feet.
This tiny theatre with an illusionistic stage proved to be inadequate for the "theatre
king" and he ordered tlJe construction of a larger theatre. Architect Erik Palmstedt
increased the size of tlJe tlleatre by incorporating part of an adjacent wing of the palace. The auditorium was remodeled again in 1785, but the theatre fell into disuse
shortly tllereafter. The castle is now a museum featuring a collection of paintings of
Swedish monarchs. '2

Gripsholm Theatre Wing Change
Gripsholm theatre is the most recent and the smallest of
the three extant theatres (see sidebar); its wing change
mechanism is also the simplest. This theatre uses the
typical central shaft and drum. With only two wings in
each of the four banks the mechanism is reversible since
the stage technicians do not have to connect a different
set of wing trolleys to the central shaft for each change.
Each wing unit consists of a trolley with two grooved
wheels, which ride on rails, located on raised platforms
in the sub-stage area and a wing ladder, which can be removed from the trolley for maintenance. The \\~ng frame
passes through the stage floor and requires a relatively
wide slot for its movement as shown in figure 3. Each
trolley has hooks mounted on both its onstage and offstage ends. Aring in the end of a rope connected to the
central shaft is connected to the onstage trolley hook. A

rope with rings on both ends connects the offstage ends
of the trolleys in each bank; tllis rope passes around a
horizontal pulley offstage of the trolleys allOWing one unit
to be pulled offstage as the other is pulled onstage. All of
the hooks and rings are bound with leather to eliminate
the metal-to-metal noise.
Arope loop attached to the large drum on the central shaft allows a stagehand to rotate the drum and shaft,
thus pulling one set of wings onslage and the other set
offstage as shown in figure 4. The mechanical advantage
of this system is the ratio of the diameter of the shaft to
the diameter of the drum. AQuickTime movie of the \~ng
